The number across the screen here. Brant, people may not be as familiar with you. But you're about to make your feature film debut. Tell us about that. It's called "the starter game." It's a spoof to "the hunger games." I play dale, a spoof of liam hemsworth. Going to be hilarious. Already done? Going to be in films SEPTEMBER 8th. I have no time to do anything else. Robin, I know you love the dancing shoes. My girls at home would be jealous. I heard you have a closet set aside for just one particular sneaker? Yes. What is this about? I have an obsession for jordan, the sneakers. I have pretty much all of them. Derek's thinking of the choreography. I have a specific closet for them. I think bill has a fascination with shoes. We know you're one of the funniest guys in the world. I learned from your bio that you will do anything to attract the ladies. Pretty much. I meant to say attract. I was never convicted of the attack. How will you attract -- not attack -- the judges' attention? I think it's going to be difficult because they're looking for precise movements.

You know. I can feel it already. Bill nye, you were the biggest surprise to me of everyone on this stage. The science guy, doing the dance. How are you going to apply that knowledge to the dance floor? It's all physics. It's all study of motion. I got something going that you may not be aware of. I'm sure I'm not. Yeah. I was telling you. It's my secret weapon. How is your physics? It's outstanding. Outstanding. I want you to expand on that.

I didn't say that. But I think there will be a theme. I've got a choreographer. I would like to see a new move, like the test tube. Ng it. We're going to tear it up. I will say -- I like our chances. This is our chance to -- awfully good. I'm feeling great. As you should. It's really exciting to see everybody. This is a blast.
